Abstract :
A multi-element oscillator with a quasi-optical resonator is reported. The resonator consists of a Fabry-Perot cavity with a grooved mirror. It has capability for power-combining of solid-state sources in the millimeter-wave region, X-band models consisting of Gunn diodes or GaAs MESFETs are demonstrated. Power-combining and frequency-locking of 18 diodes and six FETs have been successfully observed. A 50-GHz-band Gunn diode oscillator using the resonator is also reported.<>
